Melting butter is a physical change. Although the state of matter changes(solid into liquid), it is still the some substance.
Melting of butter is a physical change.
Physical.
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)

During melting the chemical structure is not changed; but rusting involve chemical rreactions.

Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
Melting in a warm atmosphere is a physical change; but the oxydation in air or the thermal degradation of butter are chemical changes.
